Abstract: 376,275. Ventilating vehicles. BOSSU, P., Riel-les-Eaux, Cote d'Or, France. March 26, 1931, No. 9258. Convention date, March 26, 1930. [Class 137.] In a method of ventilating vehicles, the windows and doors are normally kept closed, and filtered fresh atmospheric air is blown in, and the air is thermally treated as a result of an isothermal compression followed by an adiabatic expansion, the compressor and expansion members, provided with a radiator between them, being mechanically coupled. Atmospheric air is drawn into a compressor 9, Fig. 1, by way of a filter 13 and thence passes through a radiator 14 into an expansion member 10. The cooled air is then distributed to the vehicle by pipes 17, 18 the outlets from which may be masked by a screen 20. The compressor and the expansion member are both connected to a shaft 11 driven by a motor 8. In a modification, Fig. 2, the outlet 25 from the compressor is controlled by a fourway valve 24 so that the compressed and heated air may be passed direct to the vehicle by way of a pipe 26, through a heater 28 to the vehicle by way of pipes 27, 15 or through the radiator 14 and expansion member 10 as before according to the temperature or the season. In a further modification the compressor is formed in two sections which may be coupled bv a clutch, so that when the air is being supplied to the vehicle either direct or through the heater 28, only the first section which produces a slight compression is used. The clutch may be controlled manually or by means of a thermostat within the vehicle.

Part of the coursewise extent of seamless circularly knitted fabric (e.g. the sole S and, if desired, the high splice of a sock) is of double layer fabric, namely fabric 11 (outer fabric) of successive courses of one-yam y of, say, wool and fabric 12 (inner fabric) of successive courses of another yarn z of say, cotton, the two yarns being interknitted along each side of the double layer portion, in at least one wale of a single layer portion which is knitted from at least one of the yarns and constitutes another part of the coursewise extent of the fabric. Over the double fabric areas the yarn y is knitted as outwardly facing stitches on alternate needles in alternate courses and yarn z is knitted as inwardly facing stitches on the intervening needles in the intervening courses. In the leg L and instep I, both yarns may be knitted, to form plain two-feed fabric, Figs. 1 and 3, or two-feed rib or links-links fabric, Figs. 2 and 4, the yarns being selectively floated at selected stitches, or groups of stitches, to produce two colour designs. Alternatively, Fig. 5, the leg and instep may be of single-feed fabric of yarn y, the yarn z being knitted into one or more junction wales such as 4, 5, at each side of the sole; one or more intermediate junction wales may be provided, e.g. down the centre of the sole. The yarn z is either cut-off in each course, or is floated across the instep, the floats being subsequently trimmed out. The double sole may be narrower than, of the same width as, or wider than the heel, extending on each side beyond the point P thereof. The double fabric area may be widened or narrowed as desired. The top R may be of rib fabric, or of rib and plain fabric containing elastic threads. Heel H and toe T are knitted by reciprocation with progressive narrowing and widening to form gores G. The fabric may be produced on a twofeed superposed cylinder machine having double ended needles and links-links patterning mechanism. There are described arrangements of sliding and cams such that, on the instep side, all needles are in the lower cylinder and knit at both feeds whilst, on the sole side, alternate needles are transferred to the upper cylinder and knit only at the second feed, the intervening needles remaining in the lower cylinders and knitting only at the first feed. The stitch lengths of top and bottom cylinder needles on the sole side are so controlled that the sole fabrics balance the instep fabrics on one another.
